Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 76

Which of the following statements is false about OSPF area partition?

Answer options

• A. The link state databases (LSDBs) of routers are the same in the same OSPF area.
• B. OSPF area partition can reduce the LSDB size of the router.
• C. Area 0 is the backbone area, and other areas must be connected to this area.
• D. Only area border routers (ABRs) can function as the autonomous system boundary routers (ASBRs).

Correct answer: B

Explanation

Option B is correct because OSPF area partition does not reduce the LSDB size; rather, it helps in managing the routing efficiently. The other statements are accurate: A is true as routers in the same area share the same LSDB, C is correct since Area 0 is essential for OSPF operation, and D is valid because only ABRs can function as ASBRs.
